Scour pits of volcanic Martian ash
Click for original image.
Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on June 16, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The science team describes this as “clusters of scour pits,” which means the pits here were formed by the prevailing winds, which according to a global analysis of dunes on Mars, is probably blowing from the west to the east at this location.
This image only covers a small section of these scour pits. The full field extends about 20 by 18 miles across, and appears to be the southeastern flank of a mile-high dome. The scour marks could therefore also be evidence of some sagging of this material downhill along that flank.
It is also possible that the flow of the prevailing winds across this southeastern downhill slope is causing the pit formation. Unlike this flank, the rest of this dome is relatively smooth.

Israel’s Pearl Harbor
The Israeli UN ambassador and his staff wearing
yellow stars to shame the world’s diplomatic com-
munity for its willingness to appease mass murderers.
For Israel, it is now quite apparent that the mass murder by Hamas of more than a thousand Israeli civilians, including women, children, and babies, was not perceived as just another terrorist attack requiring a measured and surgical response.
No, in this case the entire nation of Israel, from the secular left to religious right, has finally recognized that Hamas had long ago declared war on the Jewish people, and the massacre on October 7th was its way of underlining that state of war.
Israel is now responding in kind, just as the United States did after Pearl Harbor. After that attack on December 7, 1941, American were resolved that they were in a war of survival that could not end until the Axis powers of Germany and Japan were utterly obliterated. There would be no ceasefire or negotiations, as had happened at the end of World War I.
For the Israelis, October 7th is their day of infamy. It is for this reason that the Israeli ambassador put on a yellow star yesterday, similar to the Star of David the Nazis forced Jews to wear, but with the words “Never Again” emblazoned thereon. He then bluntly told the appeasers at the United Nations:

In a pattern that is beginning to be almost routine, on October 27, 2023 the Mars helicopter Ingenuity completed its 64th flight on Mars, flying 1,348 feet at a speed of 13 mph for 139 seconds at an altitude of 39 feet.
As with most of its recent flights, the distance and time was slightly longer than the flight plan, likely because the helicopter took extra time finding a good landing spot.
On the overview map above, the green line marks the flight path, and the green dot the helicopter’s present position. The blue dot marks Perseverance’s present position. The yellow lines indicate the area covered by the color image to the right, cropped, reduced, and enhanced to post here. This image was taken by Ingenuity just a few seconds before landing, and looks across the floor of Neretva Vallis, where Perseverance will soon be traveling.
On the Space Show tonight
Tonight I will be doing another long appearance from 7:00-9:00 pm (Pacific) with David Livingston on The Space Show. I hope my readers tune in and, more importantly, call in with questions.
When I scheduled this with David several months ago, I told him my expectation was that Starship/Superheavy would still be on the ground due to government blockage. He hoped not. I am sad to say I was right, when I really really wanted to be wrong.
Scientists detect salts and carbon-based molecules on Ganymede
A close-up image taken during the June 7, 2021
Juno fly-by of Ganymede Click for original image.
Using data obtained during a close fly-by of Ganymede by Juno in June 2021, scientists have detected evidence of salts and organic carbon-based molecules.
On June 7, 2021, Juno flew over Ganymede at a minimum altitude of 650 miles (1,046 kilometers). Shortly after the time of closest approach, the JIRAM instrument acquired infrared images and infrared spectra (essentially the chemical fingerprints of materials, based on how they reflect light) of the moon’s surface. Built by the Italian Space Agency, Agenzia Spaziale Italiana, JIRAM was designed to capture the infrared light (invisible to the naked eye) that emerges from deep inside Jupiter, probing the weather layer down to 30 to 45 miles (50 to 70 kilometers) below the gas giant’s cloud tops. But the instrument has also been used to offer insights into the terrain of moons Io, Europa, Ganymede, and Callisto (known collectively as the Galilean moons for their discoverer, Galileo).
The JIRAM data of Ganymede obtained during the flyby achieved an unprecedented spatial resolution for infrared spectroscopy – better than 0.62 miles (1 kilometer) per pixel. With it, Juno scientists were able to detect and analyze the unique spectral features of non-water-ice materials, including hydrated sodium chloride, ammonium chloride, sodium bicarbonate, and possibly aliphatic aldehydes.
The data indicated that the salts and organics were most concentrated in Ganymede’s equatorial regions, which are less impacted by Jupiter’s strong magnetic field. The scientists think these materials originally came from the brine of an underground ocean that somehow reached the surface, though this hypothesis remains unconfirmed.
Chinese crew completes five-month mission on Tiangong-3 after return to Earth
The new colonial movement: A three-man Chinese crew successfully landed today in north China in their Shenzhou capsule, completing a five-month mission on the Tiangong-3 space station.
The full mission length was 154 days. China claims that one of the astronauts was a civilian, but that really means nothing considering the security required to participate in these missions.
The crew that has taken over on Tiangong-3 are expected to do a mission of comparable length, probably pushing the length to six-months.

- New startup, Interlune, focused on in situ technology for lunar mining and manned operations
Two of the company’s founders come from Blue Origin, while the third is Apollo astronaut Jack Schmidt, the only actual geologist to walk on the Moon.
- Visual maps showing who has put the most satellites in orbit in 2023, here and here
Not surprisingly, the maps make it obvious how much SpaceX now dominates the space industry.
- An image showing three different next generation Russian manned capsules, all under development
For an assembly production floor, the image shows remarkably little activity, with no workers and very little on the floor itself. Russia might be building these, but I bet the work is going more slowly than anything Blue Origin has done, and that is very slow indeed.

Chandra X-rays a giant hand in space
Click for original image.
Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken by the Chandra X-ray Observatory, with data from the orbiting IXPE producing the lines that indicate the orientation of the magnetic field lines.
The image was part of research studying what the scientists call Pulsar Wind Nebulae (PWNe).
[E]arly-on when the new-born pulsar is still deep in its parent supernova remnant, or at late times after it has escaped to the relatively uniform interstellar medium, the pulsar wind is often uniform around the pulsar spin or velocity axis. In projection on the sky such structures have bilateral symmetry, that is, the two halves mirror each other. This makes them look (vaguely) like animals. This has led to many PWNe collecting animal monikers (‘The Mouse’, ‘The Dragonfly’, ‘The Rabbit’ – we are guilty of some of these…).
In between these early and late phases, the story is often more complex and the PWN interaction with the supernova shock wave leads to complicated morphologies. One of the prime examples is the PWN in the supernova remnant RCW 89 (also known as MSH 15-5(2)). Here the complex interactions form the PWN into the `Cosmic Hand’. Wanting to map the magnetic fields which structure this hand, the IXPE team took a long hard stare at MSH 15-5(2) and its central pulsar.
The scientists admit that the match between IXPE’s data and the structure of the hand is not really a surprise, but confirming the match was necessary if they are ever going to figure out the fundamental laws that govern magnetic fields, laws that presently are not well understood, at all.
Don’t forget: The protesters supporting the Hamas mass murderers are all Democrats
As Israel now ramps up its offensive against Hamas in Gaza, slowly but steadily moving tanks and troops into the strip from numerous directions, protests by supporters of Hamas’s mass murders on October 7th have exploded in numerous locations in the United States and elsewhere.
To the right are screen captures from two very large protests, the top showing a demonstration of an estimated 7,000 pro-Hamas protesters taking over the Brooklyn Bridge in New York on October 28, 2023. In the video at one point you can read a sign that clearly says, “Our soldiers will not be held accountable for anything.”
The second picture is from a protest in Chicago. The demonstrators at this moment are chanting “From the river to the sea, Palestine will be free!”, a chant that has always meant in plain language, “We will kill all the Jews in Israel because Allah said only Muslims can live there.” It is also written into the Hamas founding charter, which states unequivocally that it “owes its loyalty to Allah, derives from Islam its way of life, and strives to raise the banner of Allah over every inch of Palestine.”

A spiral galaxy giving birth to a lot of stars
Click for original image.
Time for another cool galaxy image! The picture to the right, reduced and sharpened to post here, was taken by the Hubble Space Telescope, and shows what some informally refer to as the “‘Spanish Dancer Galaxy’ because the “vivid and dramatic swirling lines of its spiral arms … evoke the shapes and colours of a dancer’s moving form. ”
Though this galaxy’s two main arms cause it to resemble a barred galaxy, it lacks a central bar, suggesting it is young. The numerous reddish and pink regions in the arms, all of which are thought to be star-forming regions, also suggest the galaxy is young, still giving birth to many stars.
It is located about 60 million light years away, and is part of what scientists label the Doradus galaxy group, which contains less than a hundred galaxies. In comparison, a galaxy cluster is much larger, containing hundreds to thousands of galaxies.
Two mouse embryos successfully grown on ISS
Taken from figure 2 of the paper
In a paper just published, scientists reveal that in 2021 they successfully grew two mouse embryos in weightlessness on ISS, suggesting that “perhaps mammalian space reproduction is possible, although it may be somewhat affected,” as they note in the conclusion of their paper [pdf].
From the papers abstract:
The embryos cultured under microgravity conditions developed into blastocysts with normal cell numbers, ICM, trophectoderm, and gene expression profiles similar to those cultured under artificial-1 g control on the International Space Station and ground-1 g control, which clearly demonstrated that gravity had no significant effect on the blastocyst formation and initial differentiation of mammalian embryos.
The images to the right come from the paper’s second figure, and compare the blastocysts from a ground control (top), an 1g artificial sample on ISS (middle), and the weightless result (bottom).
The experiment has many uncertainties, with the low number of embryos tested the most important. Quoting the paper’s conclusion again, the possibilities of refining this experiment for better results are great:
Unfortunately, the number of blastocysts obtained from the ISS experiment was not abundant; and we have not been able to confirm the impact on offspring because we have not produced offspring from embryos developed in space. We believe that the ETC [the experiment itself] will allow blastocysts to be frozen on the ISS if a cryoprotectant is used in place of PFA [a solution of formaldehyde]. Then, the frozen blastocysts could be brought back to Earth for transfer to a female recipient, and the viability of the blastocysts could be evaluated. Moreover, we could design a device to launch frozen oocytes and spermatozoa to the ISS, where in vitro fertilization experiments could be performed in microgravity. The use of this approach would be cheaper. Furthermore, the study of mammalian reproduction in space is essential to start the space age, making it necessary to study and clarify the effect of space environment before the ISS is no longer operational.
Despite the uncertainties, these results are significant. They suggest that human reproduction in zero gravity is possible, which also suggests it will be even more possible in lower gravity environments like the Moon or Mars.
An infrared view of the Crab Nebula by Webb
Click for original image.
Using the Webb Space Telescope astronomers have taken the first detailed infrared image of the Crab Nebula, the remnant from a supernova that occurred in 1054 AD.
The two pictures on the right compare Webb’s false color infrared view with a natural light Hubble image in optical wavelengths, taken in 2005. From the press release:
The supernova remnant is comprised of several different components, including doubly ionized sulfur (represented in red-orange), ionized iron (blue), dust (yellow-white and green), and synchrotron emission (white). In this image, colors were assigned to different filters from Webb’s NIRCam and MIRI: blue (F162M), light blue (F480M), cyan (F560W), green (F1130W), orange (F1800W), and red (F2100W).
In comparing the images, it appears the scientists chose colors for the Webb image to more or less match those of Hubble’s natural color picture. However, as the press release notes:
Additional aspects of the inner workings of the Crab Nebula become more prominent and are seen in greater detail in the infrared light captured by Webb. In particular, Webb highlights what is known as synchrotron radiation: emission produced from charged particles, like electrons, moving around magnetic field lines at relativistic speeds. The radiation appears here as milky smoke-like material throughout the majority of the Crab Nebula’s interior.
This feature is a product of the nebula’s pulsar, a rapidly rotating neutron star. The pulsar’s strong magnetic field accelerates particles to extremely high speeds and causes them to emit radiation as they wind around magnetic field lines. Though emitted across the electromagnetic spectrum, the synchrotron radiation is seen in unprecedented detail with Webb’s NIRCam instrument.
The release also notes this remarkable but somewhat unfortunate fact:
Scientists will have newer Hubble data to review within the next year or so from the telescope’s reimaging of the supernova remnant. This will mark Hubble’s first look at emission lines from the Crab Nebula in over 20 years, and will enable astronomers to more accurately compare Webb and Hubble’s findings.
In 2005 repeated Hubble images of the Crab revealed that its filaments and radiation were stormy, with constant activity. The scientists actually produced a movie of those changes. It was expected that new images would be taken at regular intervals to track that activity. Apparently it was not, either because no scientist was interested or the committee that assigns time on Hubble decided this wasn’t important enough reseach.
SpaceX successfully launches another 22 Starlink satellites
SpaceX early this morning successfully launched another 22 Starlink satellites, its Falcon 9 rocket lifting off from Vandenberg in California.
The first stage completed its seventh flight, landing on a drone ship in the Pacific.
The company has another Starlink launch scheduled for later today, taking off from Cape Canaveral. UPDATE: Aborted at T-30 seconds for a technical issue, and rescheduled for October 30, 2023.
The leaders in the 2023 launch race:
77 SpaceX
48 China
14 Russia
7 Rocket Lab
7 India
American private enterprise now leads China 89 to 48 in successful launches, and the entire world combined 89 to 77. SpaceX by itself is now tied with the rest of the world (excluding American companies) 77 to 77.
Intuitive Machines delays launch of its Nova-C lunar lander two months
Intuitive Machines yesterday announced that it has decided to delay the launch of its Nova-C lunar lander from in November launch window to a new window beginning on January 12, 2023.
The company did not elaborate on the reasons for the delay. However, executives warned at a media event Oct. 3 that “pad congestion” at LC-39A could delay their launch. The mission has to launch from that pad, rather than nearby Space Launch Complex 40, because only LC-39A is equipped to fuel the lander with methane and liquid oxygen propellants on the pad shortly before liftoff.
That pad is used for Falcon 9 crew and cargo missions to the International Space Station as well as Falcon Heavy launches. The pad is scheduled to host the Falcon 9 launch of the CRS-29 cargo mission Nov. 5 followed by a Falcon Heavy mission for the Space Force in late November. Converting the pad between Falcon 9 and Falcon Heavy launches can take up to three weeks.
The landing site is indicated by the green dot on the map of the south pole to the right. Note that this landing will be the closest to the south pole yet, though not at the south pole. It will also be the first to land next to a crater that has a permanently shadowed interior, though Nova-C will not be able to enter it because it carries no rover and is only designed to last through the first lunar day.
Based on the present launch schedule, Astrobotic now gets the first chance to successfully land a privately built lunar lander. It is scheduled to launch on December 24, 2023 on a Vulcan rocket. The Japanese company Ispace attempted and failed to land its Hakuto-R1 spacecraft in April.
